There’s a lot of music that is hard to find on popular digital distribution networks like Spotify. They have gotten better to be honest but I still have vinyl records where there’s either not a digital version or more likely there is somewhere but it’s taken from a record. Or even taken from the original mastering and not remastered for digital which does make it sound awful compared to the original mastering. This was a huge problem in the early 90’s with CD’s and why so many CD’s from that era sound awful. Most of the more popular albums and quite a few niche ones have since been remastered for digital. But there’s a lot of obscure music that hasn’t been remastered for financial reasons or the masters don’t exist.

For new music recorded digital a vinyl record will probably sound worse really.
